A Letters Patent No. 83,618, dated November 3,1868.

IMPROVEMENT IN WRENCH.

@upon carriages, with the wheels; and I do hereby declare that the following is an exact and full description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

'I lhe nature of my invention consists in the construe tion and attachment of a wrench to the axle-nuts and wheels of carriages, said wrench having adj ustablc lixtures,posscssing the functions of fastening to the nut, upon the extremity of the axle, in connection with the l wheel A, which is also coupled with the nut, and using the wheel as the level', in turning the nut on or oi the axle, 'without greasing the hands ofthe operator in the act of lubricating the carriage-axle; and to enable others skilled in the art to make and use my invention, `I will proceed-to describe its construction and operation.

Figure 1 represents the wrench, attached both to the axle-nut and wagon-wheel'.

The wrench is seen as a whole in Figure 2 and Figure 3.

Figure 4 and Figure 5 are detached sections of fig.

Construction.

.As 'seen in fig. 2, I take out the guide-bolt or screw a from the right .jaw E, as seen in fig. 5, and locate the jaw E underneath the section U, seen in iig. 4, and retain the same by means of the bolt a, a thread beingr Gut upon this lower extremity.

Y I now insert the spoke-holder, section D, upon the front portion of section C r, it having an aperture and set-screw, l-I, as secu in fig. 2.

rIhe holder D is adjustable upon the section O r, or the section D may be adjusted with a longer screw, H I, as seen in iig. 3, the section() having the projection e attached, and the adjustable screw H I passing i through it, also through the rear portion of section D, entering between the two parts C and D, if necessary;

or the left extremity of the screw H I may be connected to the rear portion of section D, in a manner similar to the construction of the adjustable screw F, as seen in-g. 2 and iig. 5.

The front portion of the screw F is made smaller, so as to form a shoulder next to the thread cut thereon, and it passes through the jaw The front extremity is riveted, so that it cannot drawout, but turns within itsorice, as seen in g. 5.

Operation.

The wrench, as seen in iig. 2, is now placed upon .the nut ofthe axle, as seen in fig. 1. The section D, with the arm C r, extends hack between the spokes of the wheel A, andthe ouwe n embraces one spoke. The parts C and D are' pressed snugly together, and are held by the set-screw H, or by the longer screw H I, as seen in fig. 3. The right jaw E, as seen in fig. 2, is adjustable, and is moved right and left by means of the screw F.

The right and left jaws of the wrench are contracted or operated bythe screw F, the wrench being retained in its position by the hook D clasping a spoke of the -wheel A. The wheel A is now easily turned, running `the axle-nut on or off, for the purpose of lubricating the axle or'axles of carriages or wagons, using the circumference of the wheel A for the lever, and not being under the necessity of handling the nut and blackening the hands, as before stated. l

What I claim, and desire to secure by ent, isl The above-described wrench for axle-nuts of carriages, the whole constructed and operated substantially as andfor the purpose specified.
